PELVIS-SHOULDER MOVEMENT VARIABILITY AND CUETIP MOTION DURING THE WARM-UP AND FINAL STROKES IN POOL
Keywords: pool, variation, variability, consistence
AbstractThe purpose of this study was to investigate the variation and variability of cuetip, shoulder and pelvis on stop shot, push shot and draw shot during warm-up strokes (W3, W2, W1) and final stroke (FS). Eight cameras were used to determine three-dimensional motions of cue, shoulder and pelvis for a pool world cup championships winner. The results showed that the largest variation was presented in the final stroke as well as the greatest consistence through trials. Variation of shoulder and pelvis was supposed an essential factor for a pool shoot. The cuetip, shoulder, and pelvis all demonstrate the similar pattern with greatest variability in first warm stoke and greatest consistence on the final stroke. The variability will converge to from the warm-up strokes to the final stroke.
